    • Animating Peer-Level Annotations Within Web-Based Multimedia 

      Bulterman, Dick (The Eurographics Association, 2004)
      The TabletPC is an example of a new generation of user interface device where pen-based manipulation of information is integrated directly into a user s workflow. Using the TabletPC's existing pen and electronic ink systems, ...
    • Authentication of Volume Data Using Wavelet-Based Foveation 

      Kankanhalli, M. S.; Chang, E.-C.; Guan, X.; Huang, Z.; Wu, Y. (The Eurographics Association, 2001)
      3D volume data has been increasingly used in many appli- cations. The digital nature of the data allows easy creation, copying and distribution. However, it also allows ease of manipulation which can enable wilful or ...
    • Buoy Indexing of Metric Feature Spaces for Fast Approximate Image Queries 

      Volmer, Stephan (The Eurographics Association, 2001)
      A novel indexing scheme for solving the problem of nearest neighbor queries in generic metric feature spaces for content-based image retrieval is proposed to break the 'dimensionality curse.' The basis for the proposed ...
    • A Chinese Remainder Theorem Oriented Information Hiding Scheme 

      Chang, Chin-Chen; Lu, Tzu-Chuen (The Eurographics Association, 2004)
      Steganography is an information hiding technique that conveys secret information in a host signal using a secret method. Only the receivers and senders know the secret information. Many researchers have proposed their own ...
    • A Component-based Authoring Environment for Creating Multimedia-RichMixed Reality 

      Abawi, Daniel; Dörner, Ralf; Grimm, Paul (The Eurographics Association, 2004)
      Applications that seek to combine multimedia with Mixed Reality (MR) technologies in order to create multimediarich MR environments pose a challenge to authors who need to provide content for such applications. Founded on ...
    • Content Based Image Public Watermarking 

      Hengfu, Yang; Zihua, Yang; Mingfang, Jiang (The Eurographics Association, 2004)
      In this paper, a content based image public watermarking technique which operates in DCT domain is proposed. First, the 8×8 DCT sub-blocks of the host image are rearranged into a Hilbert sequence in Hilbert scanning order, ...
    • Content Based Retrieval of VRML Objects - An Iterative and Interactive Approach 

      Elad, Michael; Tal, Ayellet; Ar, Sigal (The Eurographics Association, 2001)
      We examine the problem of searching a database of three-dimensional objects (given in VRML) for objects similar to a given object. We introduce an algorithm which is both iterative and interactive. Rather than base the ...
    • Door Access Control Using Human Face and Height 

      Zhang, H. X.; Ma, R. H.; Huang, W. M.; Huang, Z. (The Eurographics Association, 2004)
      Access control has much attracted research interest recently. In this paper, we propose a method using human face and height as human trait to recognize a person. We observe that eye location extracted from a human face ...
